7 movie franchises that were cancelled on cliffhangers

Among those movies in this list, I expected for "Amazing Spider-man 3". The second part had a sad ending with Gwen Stacy died. So everyone are expecting for the third one which Mary Jane might be coming. But due to unmet expectations, they decided to can the trilogy. The movie's gross is not that bad. It's just that they expected it to gross higher.
